PORTABLE STEAM HEATER.

Application filed November 13, 1922. Serial no. 600,780.-

To all whom it may concern.

Be it known that I, CLAUD M. times, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Portable Steam Heater; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and'to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to a portable steam boiler and radiator compactly arranged as a unit with a hydrocarbon fuel burner.

Heretofore combinations between-a boiler and radiator have been proposed both as closed steam systems wherein water is evaporated, and in some cases also superheated, and condensed in a radiator, the condensate being returned to the boiler; and as a hot water system having an elevated open expansion tank. The simplest arrangement of such a steam system comprises a relatively long pipe partially filled with water having heat applied to its lower end.

Another system comprises a boiler andauX- iliary super-heating coils, the steam flowing up one side of a radiator and down the other side to a condensate tank.

It is an important object of this invention to provide a portablesteam heater wherein the pressure will be maintained at substantially atmospheric pressure.

It is a further object of this invention to provide an automatic boiler feed that will function to maintain a constant levelof wa ter in the boiler as long as the'supply tank contains any water.

It is still a further object of this invention to provide means for varying the heating effect of the burner by controlling the head of fuel fed thereto.

It is an important object of this invention to provide means for discharging the flue gases from the boiler adjacent the radiator to induce a circulation of air thereabout;

It is another important oject of this invention to provide a simple automatic heater that can be easily manufactured at comparatively slight cost, and that will compare favorably with permanent steam heating plants in cost of operation and ease of adjustment to varying requirements.

Other and further important objects of this invention will b apparent from the dis closures in the specification and the accom- Y panying drawings. I

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described. 1

On the drawings:

Figure 1 is an elevation of. a preferred form of this invention with one side of the enclosure removed to disclose the] arrangement of the various parts.

Figure 2 is a corresponding top plan View with th cover of the enclosure removed.

Figure 3 is a left end View of Fig. l with the end of the enclosure removed and with parts broken away.

' Figure 5 is a slightly enlarged section of the boiler taken on the'line 55 of Fig. 2.

Figure 6 is a partial section on the line 66 of Fig. 2. i I

Figure 7 is an enlarged section on the line 77 of Fig. 1. j 'i I As shown on the drawings:

The numeral 1 refers to a common form of steam or hot water radiator having a sin gle connection 2 serving as steam inlet and condensate return 2 to a boiler 8. The radiator is supported, at the height necessi' tate'd by the boiler and appurtenances,'on a frame or standard 3 which as shown is made up of light steel T bars 4. The frame 3 also supports a feed water tank 5 having top and bottom connections 6 and 7 tothe boiler 8 at the desired waterlevel therein.

' The boiler, details of which are shown in Fig. 5, comprises a closed vessel 8 having a plurality of radiating flues 9 leading from the centralportion ofthe blottoml A heat insulated jacket 10 encloses the Wall and top of the boiler and is spaced'therefrom, outlets 11 being provided to'lead'the hot waste gases therefrom and into close proximity to the radiator 1 proper where the gases are discharged against the radiator level outer fuel tank 13 with a removable container 14 having a valve 15 in its outlet which closes when the container is lifted so that the container can be lifted out, inverted, and refilled before it becomes entirely empty. The fuel fed to the burner is maintained at the level of the bottom 16 of the container because this is the only entrance thereto for air, so that when the fuel in the outer tank 13 is above the bottom 16 the container 14 is air bound.

The burner proper comprises an annular chamber 17 containing a suitable wick 18. The chamber 17 is mounted on a vertically movable platform 19 which is guided by a support 20. A fuel pipe 21 leads from the oil tank 13 to the support and flexible tubing 22 connects this fuel pipe to the annular chamber 17. The burner control comprises a disc 28 having a spiral slot 24 in which a pin 25 secured to the platform 19 engages. Rotation of a crank 26 serves to turn the disc and causes elevation or lowering of the burner, thus altering the relative height of the Wick and the fuel level in the tank and thus regulating the quantity of fuel supplied to the burner.

A chimney 27 is mounted on the burner and moves with it. The chimney has inner apertured cylindrical members 28 and 29 regulating and mixing the air passing up the center of the burner with the products of combustion in the outer chimney assuring complete combustion by an over supply of oxygen which eliminates the possibility of generation of carbon monoxide gas. In the construction of boiler and fines shown an excess of air does not mean lowered efficiency, as all the heat given out by the burner is either transferred to the boiler or is discharged along the radiator sections through the outlets provided.

The operation of the boiler is intended to be controlled by the feed water tank and to be maintained at or near atmospheric pressure by a relief valve in the radiator. hen the water level in the boiler falls below the openings therein to which the connections 6 and 7 from the feed water tank are attached, air or steam enters the upper connection 6 and releases water from the air-bound tank through the lower connection 7 until the openings are again covered.

Thus as long as any water remains in the tank the boiler water level is maintained at. a definite point; so that the only possible variables are the burner adjustment and the amount of radiation, the former under manual control and the latter subject to the room temperature and humidity.

In operation steam is generated in the boiler and passes into the radiator, where it remains until it is condensed, the condensate flowing back to the boiler to be reevaporated.

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. A portable steam heating apparatus comprising a hydrocarbon burner, a boiler, a radiator, an insulated jacket for the boiler spaced therefrom to afford waste gas passages thereabout, and outlets for the waste gases from the boiler jacket adapted to discharge adjacent the lower parts of the radiator to induce a circulation of air thereabout.

2. The combination with a radiator, of a boiler connected thereto, an oil burner below said boiler, means adapted to introduce an excess of air in connection with said burner, and means adapted to discharge the products of combustion, together with the excess air, towards and adjacent the lower parts of the radiator.

3. A device of the class described comprising radiating means, steam generating means connected thereto, a spaced thermally insulated jacket thereabout, combustion heating means for said steam generating means, and flue outlets connected to said spaced jacket and adapted to discharge the products of combustion towards and adjacent the radiating means.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
